2004 e46 n46 mv9n46 dme changed dme same errors

had car about a year done vavle stem seals had issus befor this thourt to be headgaskit witch was all so skimmed and all new parts
i do have a nother post ill link it at end just done a code read today after putting the fuel pump relay in right place seems to be starting to make sense now as error were really random and was cutting out the dme above 3,000 rpm now it dont rev above 2,000 rpm here are errors

first post

Did all these codes come all at once? If so, I notice the iat and ect is showing as unplugged or missing a ground. Pick a simple circuit and chase it to unravel this mess. Is this car on www.newtis.info/ because my eyes cross when i stare at so many model names and engine names :(

thanks for your replay im a bit new to all this yes all the error come when i start car maybe 4 or 5 with key on engine off can u explain IAT and ECT what is this sort for ?? and yes its on tis www.newtis.info/tisv2/a/en/e46-318ci-cab/

kind regads

I think the ect would be easier since it's probably just two wires to deal with. With the key on, unplug the sensor and one of the two wires should have something around 5 volts. Next plug it back in and check the voltage on the other wire by backprobing it, it should be 0. If you read 5v on both wires with the sensor plugged in you have a bad ground or ground wire somewhere.

just been out to the car and changed the vvt sensor but got this hard error that will not clean
its 2a67 and 2a69
